IMPROVEMENT IN COTTON-CULTIVATORS.

Specification forming part of Letters Patent No. 29,166, dated July 17,1860.

To all whom it may concern:

Be it known that I, JACOB A. HARTSFIELD, of Kinston, in the county ofLenoir and State of North Carolina, have invented a new and ImprovedCultivator and I do hereby declare that the following is a full andexact description thereof, reference being bad to the accompanyingdrawings, and to the letters of reference marked thereon.

Figure 1 is a side view leaving the drivingwheel off. Fig. 2 is a planview. Fig. 3 is an end view.

The nature of my invention consists in the arrangement of deviceshereinafter described.

To enable others skilled in the art to make and use my invention,I willproceed to describe its construction and operation.

In the construction, A is the main frame, which rests in front on theaxle.

A and A are cross-bars extendingacross the main frame, and into whichare slots for the vertical postsB to movein,which posts are attached tothe scrapers E and E.

In Fig. 2, c is the metallic face 011 scrapers E and E. Gris thegear-wheel attached to the axle. C is the shaft, to which is attachedthe chopper, and which operates the same, and which shait has itshearing at a. D is the chopper. F is the guide-pole. H is the handles.

In Figs.2 and 3 sameletters show like parts.

B in Fig. 2 is the vertical adjustable posts attached to E.

In Fig.3, 0 and c are the slots in cross-bar A and A; (1, slot inrevolving shaft C, in which another chopper may be put when necessary.to is a pinion gear-wheel on shaft 0, which gears into main cog-wheel G.F is the hounds, to which guide-pole F is attached, and which are hinged on frame A, and maybe turned outofway for convenience. By means ofslots 0 and c and uprights B and B, I can raise or lower the scrapers Eand E; or I can set them closer together or farther apart as the growthof the crop or condition of the soil may require. The chopper I) mayalso be lowered or raised by means of a thumb-screw in shaft C.

In the operation of my invention as the axle revolves by the forwardmotion of the machine the cogwheel G, working in pinion 0., gives arevolving motion to shaft C, which revolves and operates chopper D,which will at each revolution cut its width out of the row of cotton orrice, thus thinning the sameas required. The machine is so arranged thatscrapers E and E willthrow the earth from both sides at the same time,it being while the thinning process is going on by means of the chopper.

My machine is operated by two horses and one hand, and will do the workof two horses and live bands in the ordinary mode ofcultivatiou.

Having thus described the nature of my invention, What I claim as new,and desire to secure by Letters Patent, is-- v The arrangement of themain frame A, the cross-bars A and A, the scrapers E and E, thegear-wheel Gr, the shaft C, the chopper 1), the guide-pole F, thehandles H, the vertical posts B and B, the slots 0 and c, the slot d inrevolving shaft, the pinion gear-wheel a, and the hounds F, the wholebeing constructed and combined as hereinbefore described, for thepurposes set forth.

JACOB A. HARTSFIELD.
